| 英文摘要 | The multiconfiguration Dirac-Fock method has been used to study interference effects between direct and resonant photorecombination (i.e. radiative and dielectronic recombination) from the ground state 1s(2)S(1/2) of H-like Ar17+ ions via doubly excited 2s(2) S-1(0), 2s2p P-3(0,1,2), P-1(1) and 2p(2) P-3(0,1,2), D-1(2), S-1(0) resonances of He-like Ar16+ ions combined with the Fano parameterization technique. In order to produce total photorecombination spectra, it is necessary to calculate the energy levels of the 1s of H-like Ar17+ ions, 1s(2), 1s2l and 2l2l' (l, l' = 0, 1) of He-like Ar16+ ions, the radiative and nonradiative properties of the doubly excited states of He-like Ar16+ ions, and the direct and resonant photorecombination cross sections from the 1s state of H-like Ar17+ ions into the ground state 1s(2) and the single excited states of 1s2l (l = 0, 1) of He-like Ar16+ ions, in detail. Based on good agreement between the present calculations and other available experimental and theoretical results, the interference profile determined by the so-called Fano parameters q and rho(2) is also shown. The results indicate that interference effects are remarkable at some resonances, especially near the doubly excited 2s2p P-1(1) state of He-like Ar16+ ions, and strongly influence the intensity of the wing of the nonresonant background in the photorecombination of H-like Ar17+ ions through comparison between the final Fano and total radiative recombination to dielectronic recombination spectra. |
